CDIIBUSTION-PROMOTING DEVICE.

Application led April 18, 1922.

To @ZZ 107mm. t muy concern:

Be it known that l, DADI Eri-emerson, a citizen ot lceland` residing atBaltimore, in the countyv ot' l )1ltiiii i'e City and State out gland.yhave invented new and useful .1.inprorcnients in loinbustion-FromotingDevises, oi which the following is a speciiication.

This invention relates to improvements in l0 'fuel eeoininni'fzers andhas for an object the provision of a device which may be installed inthe tire boi; or ,turiniceq whereby the products t i combustion .Tray bemore thoroughly coi uned and 'the amount of smoke reduced to a minimum.

rinother object ot' the invention is the provision ot a device ot thetdi-ove elmracter which proi'f'idcs an air baille at the rear end ci:the lire bor; to retard the escape of the products ot conibnstion andwhich in additionr` will direct the heat tov-Jard the walls of said lireboi; to more reaniln promote the generation ot steam.

lilith the abo and other ects in view, the invention further includesthe following novel 'feature id is ci construction, to be herein-ai morefully described, illustrated in the accomoanynig drawings and pointedout in thc appe ded claim.

I" tu the drawings:

ltigure 1 is a longitudinal sectional View through a portion ot aruruace with the invention applied.

Figure 2 is a section on the line 2 2 ot Figure 1.

Figure 3 is an enlarged longitudinal ver-- tical section ot theinvention per se.

Referring in detail to the drawingsJ wherein like characters referencedenote corresponding parts, the reference character 10 indicates thetire box of the furnace which is herein shown as of the corrugated typeand which has its rear end in communication with a smole tlue 11 and itsfront end provided with a burner 12 ot any suitable type.

The invention which is designed to supply air to the interior of thetire box comprises a head 13 which is formed by a pair oi. hollowconical members 14l and 15. These hollow conical members have theirbases surrounded by flanges 16 for the passage Ot' Serial No. 554,801.

bolts 17 by means of which the members are secured together. rllhe head13 is supported upon a suitable bracket 18 arranged within the fire boxand one section of the head, for example the section 15 is incommunication with one end of an air supply pipe 19 which is controlledby a valve 20. The pipe 19 may lead to any suitable source of airsupply, such as a compressor or blower, so that air may be suppliedunder pressure to the interior of the head 13.

The air so supplied is distributed within the lire boi; and tor thispurpose each section lf-t and 15 of the head 18 is provided with escapeopenings 21, the shape of the head and the positions ot these openingsbeing such as to direct the air outwardly against the walls of the irebox tor mixture with the products of combustion and thus facilitate theconsumption of the gases and reduce the consumption of fuel. Inaddition, the air escaping from the openings 21 forces the products otcombustion toward the walls or the tire 'box to more readily promote thegeneration of steam. The arrangement of the openings 21 ot' the section15 oli' the head is such that a greater amount of air escapes throughthis section than through the section 14 which is located nearer thetrontof the furnace. This increase of the escape oi air may be providedfor by increasing the number ot openings in the sec-tion 15 over thesection 111, or the openings may be of larger diameter. The result is,that an air battle will be provided at the rear end ot the lire bon toretard the escape of the products ot' combustion and thus permit of athorough consumption of the steam with a resultant increase ci' heat.The forward end of the section 1li is provided with a verticallydisposed batlie plate 22 which is located between the air escapeopenings and the burner 12 and acts to defiect the air outvard toJfurther aid in distributing the products or" combustion toward thewalls of the 'lire bot-z.

The invention is susceptible of various changes in its form, proportionsand minor details ot construction and the right is herein reserved tomalte such changes as properly 'fall within the scope of the appendedclaimL Having described the invention What is claimed is In thecombination With a 'furnace having a burner disposed therein in a mannerso 5 that it will play its flame horizontally, vertically disposedbrackets arranged Within said furnace, hollow perforated conical shapedmembers having their bases secured together and means supported by thebrackets in a manner to be arranged in alignment 10 with the burner,means for supplying air to the members and a defiector plate arrangedbetween the burner and the members as and for the purpose specified.

In testimony whereof I aiIiX my signature.

DADI EGGERTSON.
